Heap: Compost Tracker & Guide

Heap takes the guesswork out of composting. Whether you're managing a backyard bin, a tumbler, or a full-scale hot pile, Heap tracks your carbon-to-nitrogen ratio in real time so you get rich, dark compost — not a smelly mess.

REAL-TIME C:N RATIO CALCULATOR
Add what you toss in — kitchen scraps, coffee grounds, eggshells, leaves, cardboard, grass clippings, sawdust, straw — and Heap instantly calculates your carbon-to-nitrogen balance. A visual indicator shows whether your pile is too green, too brown, or just right. No chemistry degree needed.

TRACK MULTIPLE BINS
Manage compost bins, tumblers, worm farms, and open piles all in one place. Name each one, log turns, record temperatures, and track how each pile progresses from raw waste to finished humus.

80+ MATERIAL LIBRARY
Look up the C:N ratio for over 80 common composting inputs: fruit peels, vegetable scraps, newspaper, wood chips, manure, seaweed, dryer lint, and more. Each entry shows whether it counts as green (nitrogen-rich) or brown (carbon-rich) material.

COMPOSTING METHODS
Compare hot composting, cold composting, vermicomposting, and bokashi side by side. Heap explains the tradeoffs — speed, effort, space, and smell — so you can pick the method that fits your yard, balcony, or kitchen counter.

TROUBLESHOOTING GUIDE
Pile too wet? Smells like ammonia? Not breaking down? Attracting flies or pests? Heap's troubleshooting section diagnoses common compost problems and suggests fixes based on your pile's current C:N balance.

TEMPERATURE & TURN LOGGING
Track internal pile temperature over time to know when your hot compost is cooking and when it needs turning. Log each turn with date and notes to build a complete composting history.

WORKS OFFLINE
All your composting data stays on your device. No account required. No internet connection needed. No ads. No tracking.

ZERO-WASTE GARDENING
Heap pairs naturally with Plant Anywhere, the free garden planner with 621 crops and companion planting guides. Grow food, harvest, then close the loop by composting kitchen and garden waste back into rich soil for next season's beds.

SUSTAINABILITY MADE SIMPLE
Home composting diverts organic waste from landfills, reduces methane emissions, and builds healthy, fertile soil. Heap makes it easy to start composting and stay consistent — whether you're tossing your first banana peel or managing multiple bins on a homestead.
